| Abstract Scope |
The aluminum industry searches to understand each step of the incorporation of the alumina into the electrolyte bath in order to improve alumina feeding process. A Lagrangien model, called CuDEM and destined to simulate the feeding process is presented in this paper. The first part of this model focuses on the interaction between the spherical particles and their environment by resolving the movement’s equation using discrete element method. The second part uses the smooth particle hydrodynamics to simulate the flow and freezing of the bath during raft formation.
Each step of the simulation was validated experimentally, using spherical particles of Teflon injected into an analogue liquid. The mechanical and the thermal interactions were calibrated with room temperature and cooled solid particles respectively. |
